Has anyone successfully installed and configured 'prax' https://github.com/ysbaddaden/prax ? I have tried configuring it on multiple pc but no success.
There is pow but it works only on OSX. If any other alternative please share.
First, install Prax and configure your apps as stated on its GitHub.
To know if actually is working, ping to a desire app.
ping myapp.dev
It should ping to your loopback (127.0.0.1). If this is not your case, check again.
Then follow this steps:
1) Restart your server
2) Restart your browser. If you are using Chrome, you might need to clear the cache (as stated on: https://github.com/ysbaddaden/prax/issues/51 and Pow domains not loading in Chrome)
3) Launch the app:
http://myapp.dev/
It is important that the first time you use the http:// prefix.
If you are using Rails (which server Webrick defaults to port 3000, you should add this port to the URL, (I couldn't figure it out how to avoid this):
http://myapp.dev:3000/
- check on firefox.I had same problem in chrome, then I switched to firefox and It was working.
